To LZZ whom, it may concern: Y

Beit known that I, NATHAN SCHWAB, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Stoppers for Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specilication.

My invention relates to an improvement in Stoppers for bottles, jars, and like vessels, and in the seat adapted to receive them, and has special reference to that class known as screwstoppers57 and it consists in making the same as hereinafter described, and more particularly pointed out in the claims.

In the use of glass or other screw-Stoppers of vitreous material heretofore used, it has become a recognized fact that great danger arises from the frequently chipping off and falling down into theliquid in the bottle to be consumed as medicine, or. to be drank, small sharp portions of the screw-th read, when the stopper is firmly turned into its seat to make the bottle air-tight, and the object of my invent-ion is to overcome this serious objection by providing a screw-stopper and seat ot' such form and material as to obviate the liability ofthe chipping off of small spieula of the material and its falling into the liquid ofthe bottle, thereby endangering` the life and health of the person who consumes it, and to form a more perfect air-tight stopper for the bottle than can be made by the use of unyielding or vitreous material.

In the drawings, Figure l represents a plan view ot' my improved stopper; Fig. 2, a part vertical sectional view of the neck or seat into which the stopper is screwed. Fig. 3 shows the stopper inserted in the battle. Fig. 4 is a detail view showing the neck ofthe bottle in section before the socket is inserted. Fig. 5

shows the socket removed from t-he bottle. Fig. 6 is a plan view showing the layers of material in thestopper.

Like letters of reference refer to corresponding parts in each figure of the drawings.

A represents my improved stopper, made solid from one piece ot' rolled and compressed leather, having male screw-threads a formed on the periphery of its body. The blank from which the stopper is made is cut of suitable size and form, and has one ot' its surfaces coated with glue or other adhesive substance, and is tightly rolled together, as shown at d, on its adhesive side, with portions of its cnt end turned in to form the head. It is then compressed in a die to make it regular in shape and to form screw-threads thereon,when it is allowed to dry, and is ready for use.

B represents a bottle, which may be made in any desired shape, having a mouth, b, reenforced around its edge. The neck of the bottle is made of a length equal to the length of the screw-threaded portion of the stopperwhich it is desired to use in it, and has on its inside a recess, C, with projections c extending therein.

A socket, D, made of rolled leather formed around a mandrel, and having a vfemale screwthread on its inner side, is placed within the recess C, and is secured therein by means of glue or other strong adhesive substance, and is kept in place by the projections c, which press into its sides, and, together with the adhesive substance, prevent it from turning or working loose when the stopper is inserted or removed.

lI am aware that it is not new to form a screw-stopper of elastic material; but many of those now in use are found to be objectionable, for that they emit a disagreeable odor, which to a greater or less extent permeates the liquid of the bottle, and others are made ot' a material so loose that when the strain is brought to bear upon the stopper in screwing it in its seat in the bottle the screw-threads will crumble or break olif, and portions of it will drop into the liquid of the bottle when the stopperl is ',removed, and I do not, therefore, broadly elaiman elastic screw-stopper; but

\Vhat I do claim as new, and desire to secure by Letters Patent oi' the United States, 1s-
